What I Know Now

I'm free as a bird
I can go anywhere around the world
And it's so, so much easier, easier
Since you said goodbye
Only gotta think about me, myself and I
And I'm sure, I'm sure I don't need ya, need ya

'Cause now I live it up like every night
I have the best time of my life
But it's all a lie, I'm a little bit drunk
Maybe this ain't right but

I'm at your door standing here
It's 3 AM, I know that you're within
I shoulda listened
If only I knew then what I know now
You say we can't get back in time
Life without you don't feel right
I keep wishing
If only I knew then what I know now

What I know, what I know, what I know now
If only I knew then what I know now

So yes I'm an idiot
Guess I said a lot of things that you won't forget
But I'll change, just let me show ya, show ya
No don't say I have to go
I've been out here practicing in the cold
What to say, just let me hold ya, hold ya

'Cause I got a hole burning through my heart
And I'm not whole when we're apart
Let's take it from start
I'm a little bit drunk and I'm going to fall but

I'm at your door standing here
It's 3 AM, I know that you're within
I shoulda listened
If only I knew then what I know now
You say we can't get back in time
Life without you don't feel right
I keep wishing
If only I knew then what I know now

What I know, what I know, what I know now
If only I knew then what I know now
What I know, what I know, what I know now
If only I knew then what I know now

And I got a hole burning through my heart
I'm not whole when we're apart
And I just can't lie
I'm a little bit drunk and I need you tonight so

I'm at your door standing here
It's 3 AM, I know that you're within
I shoulda listened
If only I knew then what I know now
You say we can't get back in time
Life without you don't feel right
I keep wishing
If only I knew then what I know now

What I know, what I know, what I know now
If only I knew then what I know now
What I know, what I know, what I know now
If only I knew then what I know now
